CAUTION
Risk of damage by electrostatic discharge (ESD)
When you handle processor cards, wear a grounded
antistatic wrist strap or equivalent to protect electronic
parts. For more information, see "Avoiding damage from
static electricity" (page 208).
CAUTION
Risk of service loss
Before performing an FP cable upgrade on an FP
configured with intra-card APS (port-to-port sparing on
the same FP), ensure that both the working and
protection lines are not degraded.
Locking a port configured with intra-card APS causes
active lines to transfer traffic to the other port. During
switchover, up to up to 50 milliseconds of traffic can be
lost.
